class documentation

class CommandCollection(MultiCommand):

A command collection is a multi command that merges multiple multi commands together into one. This is a straightforward implementation that accepts a list of different multi commands as sources and provides all the commands for each of them.

Method	`__init__`	Undocumented
Method	`add_source`	Adds a new multi command to the chain dispatcher.
Method	`get_command`	Given a context and a command name, this returns a `Command` object if it exists or returns `None`.
Method	`list_commands`	Returns a list of subcommand names in the order they should appear.
Instance Variable	`sources`	Undocumented

Inherited from MultiCommand:

Method	`collect_usage_pieces`	Returns all the pieces that go into the usage line and returns it as a list of strings.
Method	`format_commands`	Extra format methods for multi methods that adds all the commands after the options.
Method	`format_options`	Writes all the options into the formatter if they exist.
Method	`invoke`	Given a context, this invokes the attached callback (if it exists) in the right way.
Method	`parse_args`	Given a context and a list of arguments this creates the parser and parses the arguments, then modifies the context as necessary. This is automatically invoked by `make_context`.
Method	`resolve_command`	Undocumented
Method	`result_callback`	No summary
Method	`resultcallback`	Undocumented
Method	`shell_complete`	Return a list of completions for the incomplete value. Looks at the names of options, subcommands, and chained multi-commands.
Method	`to_info_dict`	Gather information that could be useful for a tool generating user-facing documentation. This traverses the entire structure below this command.
Class Variable	`allow_extra_args`	Undocumented
Class Variable	`allow_interspersed_args`	Undocumented
Instance Variable	`_result_callback`	Undocumented
Instance Variable	`chain`	Undocumented
Instance Variable	`invoke_without_command`	Undocumented
Instance Variable	`no_args_is_help`	Undocumented
Instance Variable	`subcommand_metavar`	Undocumented

Inherited from Command (via MultiCommand):

Method	`format_epilog`	Writes the epilog into the formatter if it exists.
Method	`format_help`	Writes the help into the formatter if it exists.
Method	`format_help_text`	Writes the help text to the formatter if it exists.
Method	`format_usage`	Writes the usage line into the formatter.
Method	`get_help`	Formats the help into a string and returns it.
Method	`get_help_option`	Returns the help option object.
Method	`get_help_option_names`	Returns the names for the help option.
Method	`get_params`	Undocumented
Method	`get_short_help_str`	Gets short help for the command or makes it by shortening the long help string.
Method	`get_usage`	Formats the usage line into a string and returns it.
Method	`make_parser`	Creates the underlying option parser for this command.
Instance Variable	`add_help_option`	Undocumented
Instance Variable	`callback`	Undocumented
Instance Variable	`deprecated`	Undocumented
Instance Variable	`epilog`	Undocumented
Instance Variable	`help`	Undocumented
Instance Variable	`hidden`	Undocumented
Instance Variable	`options_metavar`	Undocumented
Instance Variable	`params`	Undocumented
Instance Variable	`short_help`	Undocumented

Inherited from BaseCommand (via MultiCommand, Command):

Method	`__call__`	Alias for `main`.
Method	`__repr__`	Undocumented
Method	`_main_shell_completion`	Check if the shell is asking for tab completion, process that, then exit early. Called from `main` before the program is invoked.
Method	`main`	No summary
Method	`make_context`	This function when given an info name and arguments will kick off the parsing and create a new `Context`. It does not invoke the actual command callback though.
Class Variable	`ignore_unknown_options`	Undocumented
Instance Variable	`context_settings`	Undocumented
Instance Variable	`name`	Undocumented
